It’s no secret that Indiana is one of the best states in which to start a business, with competitive tax rates, a low cost of doing business, and a variety of grant programs to help launch your business from day one. Five Fortune 500 companies have set up shop in the state to reap the business benefits, but small businesses help fuel the majority of the Hoosier economy.
If you want to become part of the approximately 500,000 small businesses that call Indiana home, keep reading. This complete guide walks you through how to form a limited liability company (LLC) in Indiana, from choosing a name to setting up a business bank account.
Why form an LLC in Indiana?
An LLC is a straightforward, easy-to-manage business entity type that gives you more protection than operating under your own name, and fewer regulations than corporations.
- Limited liability protection. The business owners’ personal assets generally cannot be used to satisfy business debts or settle legal issues.
- Flexibility in management structure. LLCs can choose to be member-managed or manager-managed and don’t have the strict management or operational requirements that a corporation has.
- Various tax election options. An LLC can choose to file taxes as a corporation or as a sole proprietor/partnership—and can even elect to be taxed as a C corporation.
- Competitive state tax rates. While Indiana's corporate income tax aligns with the national average, its individual income tax is one of the lowest in the country, making it particularly ideal for LLCs opting for pass-through taxation. In 2026, individuals pay a 2.95% rate, lowered from 3% in 2025.
The first step to register a new venture in The Hoosier State is to decide on a business structure. An LLC business structure makes sense over other entity types in Indiana if you want:
- Liability protection
- Fewer compliance requirements than a corporation
- Flexible operations and management options
- Business credibility and professionalism

How to form your Indiana LLC: Step-by-step guide
Step 1: Name your Indiana LLC
Before you can officially register your LLC, Indiana law requires you to choose a name that's distinct from any other registered entity in the state. It's fairly simple to confirm this by conducting an Indiana business search through the Indiana Secretary of State’s INBiz search portal. You can also use LegalZoom’s free name search tool below.
Free Indiana Business Name Check
Use our free name check tool to search the Indiana Secretary of State database and see if your business name is available.
By clicking "Check Availability," I agree to LegalZoom's Terms of Use. This search is a preliminary check of state databases and does not include variations or trademarks. Results do not guarantee name availability or compliance with legal requirements.
You'll also need to confirm your business name aligns with the following Indiana LLC naming guidelines to avoid your articles of organization being rejected:
- The name of your LLC must include the words “limited liability company” or the abbreviations “LLC” or “L.L.C.”
- Without special approval from the state, your LLC name can't contain prohibited terms such as “bank,” “insurance,” “trust,” or any name that implies affiliation with a government agency.
Before solidifying your business name, you should also conduct an Indiana state trademark search and a federal trademark search through the US Patent and Trademark Office. Then, do an Internet search to confirm that the name (or at least close variations) isn’t being used in a domain name or on social media profiles.
You can conduct a free trademark search with LegalZoom to identify exact matches, or a comprehensive trademark search for an in-depth look at potential conflicts.
Once you've landed on a name for your Indiana business and confirmed that it’s available and not protected by a trademark, you may want to reserve it by filing a reservation of business name application through your INBiz account and paying the $10 filing fee. Reserving your business name allows you to hold it for up to 120 days before you go through the effort of filing your Indiana LLC articles of organization.
Step 2: Choose your Indiana registered agent
All business entities in Indiana must maintain a registered agent and a registered office in the state. A registered agent is a person or entity responsible for receiving important legal and tax documents—such as service of process or notices—on behalf of your LLC.
An Indiana registered agent needs to comply with the following requirements:
- The registered agent must reside or be authorized to conduct business in Indiana, and their business office is the registered office.
- The registered office must be a street address in Indiana (a P.O. box is not sufficient).
- The registered agent must be available at their registered office during normal business hours to receive mail and notices.
An LLC entity itself can't act as its own registered agent in Indiana, but a member or an employee can. Fulfilling this role yourself can avoid registered agent service fees, but most businesses prefer to hire a professional registered agent service to save themselves the time and protect their privacy, since the registered agent must publicly disclose a location where they can be found. LegalZoom’s Indianapolis registered office meets all state requirements and offers convenient digital scans of all correspondence.
Step 3: Prepare and file articles of organization
Once you have a name and registered agent for your LLC, you're ready to officially register your LLC in Indiana. This involves filing formation paperwork called articles of organization.
Your Indiana LLC filing options are:
- Online. Create an INBiz account and follow the instructions to complete your articles of organization. Online filing fees are $95 plus a small online processing fee.
- By mail. Download, print, and complete Form 49459. When you mail your articles, make sure you use 8-½-inch by 11-inch white paper and print or type in ink. Mailed filings cost $100. Include a check or money order payable to the Secretary of State:
Indiana Secretary of State
302 W. Washington St., Room E-018
Indianapolis, IN 46204
For a domestic LLC, Indiana requests the following information:
- LLC name and email address
- The name, street address, email address, and telephone number for returning documents
- Principal business address
- Name and physical address of your Indiana registered agent (a P.O. box is only acceptable if accompanied by a rural route number)
- Duration of your LLC, which may be perpetual if there's no intended end date
- Management structure (whether member-managed or manager-managed, and whether it will be a single-member LLC)
- Name and signature of organizer
Make sure to fill out the form completely and accurately. An error in your filing may result in delays or rejection. LegalZoom’s LLC formation service adds another layer of accuracy, helping small business owners fill out and file their articles of organization with hands-on guidance if needed.
Once the Indiana Secretary of State files and approves your formation documents, they'll issue you a certificate that confirms your LLC formally exists. This certificate allows your business to obtain a federal tax ID, apply for business licenses, and open a business bank account.
Step 4: Create an operating agreement
An operating agreement is a document that outlines the way your LLC will conduct business, including ownership structure, roles, and operational procedures. Indiana doesn't require LLCs to file an operating agreement, but it’s an essential component that establishes the policies and procedures for your business.
An Indiana LLC operating agreement can be especially helpful when settling financial disputes or other potential litigation that may arise. Without an agreement in place, courts typically base settlement decisions on state law, which might not be in the best interest of your LLC and its members. Even single-member LLCs can benefit from having this document, as it can provide proof of separate business and personal assets, further establishing liability protection.
An operating agreement can include, but isn’t limited to, the following:
- LLC's name and principal address
- LLC's members' percentage interests in the LLC
- LLC's members' rights and responsibilities
- LLC's members’ voting powers
- Rules for holding meetings and taking votes
- Duration of the LLC
- Name and physical address of the registered agent
- Information about the certificate of organization
- Purpose of the business
- Members and their contribution
- The way the LLC’s profits and losses will be divided
- Procedure for admitting new members and releasing outgoing members
- Management of the LLC
- Indemnification and liability clauses
The best way to create an operating agreement depends on your specific needs and level of comfort with legal documents. LegalZoom provides an LLC operating agreement template that you can fill out yourself, but companies often choose to draft one with the help of a business attorney, as the contents of the document can impact litigation decisions. LegalZoom’s operating agreement drafting service starts at $99.
Building a business is enough work as it is. We'll help you start your LLC with confidence.
Step 5: Get your EIN and open a business bank account
The nine-digit employer identification number (EIN) allows the IRS to identify your LLC for taxes. The purpose of an EIN is to allow you to file and pay federal, state, and local income taxes, but it is also usually needed to open a business bank account and hire employees.
Multi-member LLCs generally must get an EIN, but can be optional for single-member LLCs that don’t plan on hiring employees. You can obtain your EIN by:
- Applying online through the IRS website
- Faxing Form SS-4 to 855-641-6935
- Mailing Form SS-4 to the Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999
LegalZoom also offers an EIN application service that can save you time and effort by helping you fill out the application and filing it with the IRS for you. As soon as it’s approved, we’ll send you your EIN and official documentation.
Once you have your EIN, you can open a business bank account at your preferred financial institution. A business bank account is essential for LLC owners to separate personal and business finances and protect limited liability status.
An Indiana bank may ask for all the following to open an LLC bank account:
- EIN or SSN
- Certificate of formation
- Description of business
- Initial deposit
- Personal information for everyone that will be on the account
- Operating agreement
You can use your bank account for receivables, vendor payments and expenses, and opening a business credit card.
Step 6: Register for Indiana state taxes
When paying taxes, a single-member LLC in Indiana files similarly to a sole proprietor, and a multi-member LLC files as a partnership by default. Both are considered "pass-through" entities. This means that rather than paying corporate taxes, you report your gains and losses on your personal tax returns. However, you can elect to be taxed as a corporation with the IRS instead. Indiana's state income tax rate for tax year 2025 is 3% for individuals and 4.9% for corporations.
Depending on the nature of your business, you may need to register for state sales, use, and income taxes with the Indiana Department of Revenue (DOR). You can either register from your INBiz account or by filling out Form BT-1. The single business tax application helps you register for a number of taxes, including sales tax, withholding tax, food & beverage tax, and local income tax by county.
For example, if you plan to sell goods in Indiana, you need a Retail Merchants Certificate, which you can apply for through Form BT-1 for a $25 fee. This certificate essentially provides your business with a tax ID—or tax-exempt—number. Indiana’s flat sales tax rate is 7%.
Step 7: Get business licenses and permits
Now it’s time to get your federal, state, and local licenses and permits. Here are some examples of what you may need:
- Federal permits. If your business operations fall under the regulations of a federal government agency, you’ll need to apply for the relevant permit. For example, if your operations involve transporting or selling livestock, you may need a permit from the U.S. Department of Agriculture. Refer to the U.S. Small Business Administration’s list of federal permit types.
- State agency-issued licenses. Indiana doesn't have a general business license, but you may need to get an industry-based license or professional license. With over 400 different licenses, permits, certifications, and other permissions depending on the type of business, the Indiana Professional Licensing Agency is a great source to locate the right license based on your profession.
- Local licenses. The city or county in which your business operates may issue separate licenses or permits for certain activities. For example, Indianapolis issues permits for commercial parking lots, childcare centers, hotels, and more. Check with your local government to understand what permits or licenses your LLC may need.
Regardless of the industry, Indiana requires all businesses to file business tangible personal property forms annually with their county or township’s assessor’s office. Business tangible personal property is the value of all property that your business uses, excluding real estate and computer software. You can file online through the Indiana Personal Property Online Portal or contact your local assessor’s office to access a paper form. The form is due annually by May 15.
LegalZoom helps you handle every step—from choosing a business name to filing paperwork with your state.
After formation: Maintaining your LLC in Indiana
Registering your LLC gives you a legal foundation to conduct business. Plan to keep your LLC compliant and in active status by doing the following:
- Pay all necessary taxes. This might include making quarterly tax payments at both the state and federal levels. The amount of taxes you pay will depend on factors like how you choose to file (as an individual or a corporation), local tax rates, and business-related taxes, such as sales tax.
- File a business entity report with the Indiana Secretary of State every two years. The report is due every other year within the anniversary month of the LLC's formation. The filing fee is $31 online through your INBiz account or $50 by mail.
- Maintain a registered agent for your business, and notify the Secretary of State if your registered agent or the registered office address changes.
- File your business tangible personal property return, due every year by May 15.
- Keep a compliance calendar with specific due dates for things like taxes, your business entity report, and business license and permit renewals.
If you miss important deadlines, there may be legal or financial penalties. For instance, failure to file your business entity report may result in administrative dissolution or the revocation of your LLC—meaning that you won’t be able to legally operate in Indiana.
Stay organized and meet all your deadlines with LegalZoom’s business compliance services, which include notifications for upcoming report due dates, help with amendment filings for business changes (like your registered agent), customized compliance alerts, and more.
Common mistakes to avoid when forming an Indiana LLC
With so many tasks to complete, it’s easy to overlook a step or make a mistake along the way. Here’s a list of common errors so that you can avoid them for your own LLC formation process.
- Name-related errors. Make sure that your business name is distinguishable from other registered entities in Indiana and not protected by a state or federal trademark. (Hint: Check multiple name spellings and variations.) Follow all Indiana LLC naming requirements.
- Failing notify the Secretary of State of registered agent changes. If your registered agent or the registered office address changes, you must notify the Indiana Secretary of State immediately to avoid falling out of compliance. You can file a statement of change of registered agent by mail or online (no filing fee).
- Operating agreement oversights. To avoid any omissions in your operating agreement, it’s recommended that you use a template or a professional service (LegalZoom offers both). This ensures that all potential issues and situations are addressed.
- Tax registration gaps. Fill out Form BT-1 carefully and accurately to ensure that your business registers for all applicable taxes. Additionally, consult a tax professional about the right tax elections for your business (pass-through vs. corporate vs. S corporation). And don’t forget to file your business tangible personal property return.
- Overlooking business licenses. Many businesses will need licenses or permits to operate legally. Check with relevant federal, state, and local agencies to determine what your LLC needs. LegalZoom’s business license report and management service is the easiest way to do this, as we provide a customized summary of all the licenses you need at every government level.
DIY vs. professional LLC formation: Which is right for you?
While going the DIY route can save money, it might not be ideal for busy business owners who have a lot on their plate. DIY may be right for you if you feel comfortable navigating state agency websites, registration portals, and lists of forms. But this takes significant time, plus filling out paperwork requires a keen eye for detail to ensure accuracy.
LegalZoom simplifies the Indiana LLC formation process, helping you file the right paperwork with the correct state agency. We offer three different formation packages, starting at $0 + state filing fees. You can choose one of our bundles or choose from our many business services to assist with specific areas of your business formation.
Starting a business takes courage. LegalZoom makes sure the legal details don’t stand in your way, from the day you register until the day you retire.
Next steps after forming your Indiana LLC
There are a few other steps you should consider after forming your Indiana limited liability company.
Register a domain name
Even if you’re not ready to make a website, you can at least buy a domain name to reserve it. You can do this on sites like Wix, GoDaddy, and Bluehost. Having a domain that matches your business name will make it easier for prospective clients to find your business online and can help to build credibility.
Obtain a certificate of good standing
Once you've officially registered your limited liability company, you may want to order a certificate of good standing, also called a certificate of existence in Indiana. You're not required to have this document, but it proves to potential partners, investors, lenders, and customers that your business legally exists and has authorization to operate in Indiana.
You can order this certificate from the Indiana Secretary of State through your INBiz account for a $27 filing fee plus an online processing fee. You can also use LegalZoom's certificate of good standing service, and we'll file for you and deliver it once we've received it from the state.
Consider a foreign LLC
Registering a domestic LLC in Indiana only authorizes you to legally operate within The Hoosier State. If your business is booming and you believe it could benefit from expanding into another state, consider registering it as a foreign LLC there. The cost of registering a foreign LLC will vary from state to state, but it may be worth the effort to widen your customer base.
